SHOW-WINDOW SHELVING.

SPECIFICATION forming part of Letters Patent No. 349,117, dated September 14, 1886.

Application filed September 8, 1885. Serial No. 170,490.

To all whom it may concern:

Be it known that I, WILLIAM OswELL, of Boston, in the county of Suffolk and State of Massachusetts, have invented a new and Improved Show-\Vindow Shelving, of which which the following is a full, clear, and exact description.

My invention relates to the construction of a shelving for show-windows or stores, and its object is the formation of a series or system of the several points of connection of ashelf with the posts or uprights being the same distance from the lower ends of the posts or uprights, substantially as hereinafter morefull y set forth, and pointed out in the claims.

Reference is to be had to the accompanying drawings, forming part of this specification, in which similar letters of reference indicate corresponding parts in both the figures.

Figure 1 is a perspective view of the interior of a show-window supplied with my improved shelving, two forms of shelving being shown in an upright position; and Fig. 2 is a sectional side View of the shelving when folded down so that the supporting-bars are in a horizontal position.

Referring now to the general construction illustrated in the drawings, A represents the flooring of any ordinary form of showwindow; B, the front glass, and 0 one of the side walls.

The main shelving (shown asin upright position within the show-window just referred to) is mounted on a frame-work consisting of (No model.)

the posts are raised, as shown in Fig. 1, they will constitute the four corner-supports of the shelves at m, which are formed with downwardly-projecting lugs 0 0 at each corner, and are connected to the posts a, b, c, and d by bolts k, which pass through apertures formed in the meeting lugs e and o.

In order to hold the shelving in an upright position, I attach a cord, q, to the upper shelf and run it over a sheave, 7', carried by ablock, 1", secured to the ceiling of the window, the free end of the cord being secured to a cleat or other fastening device.

Such a set of shelving as I have described may be lowered outward from the top to any desired angle and fastened in position by the cord q; but the shelves m at will always be in a horizontal position, because of the fact that their pivotal connections with the bars a, b, c, and d are atthe same distance from the lower. ends of the bars, and consequently as the bars fold down the pivotal connections of each shelf will pass through corresponding arc s, thereby maintaining the shelf in a horizontalplane, irrespective of the angle at which the bars are inclined.

Upon the side 0 of the window I show a smaller set of shelves mounted 011 two bars that are pivoted to the sidewall at s s, each bar I being formed with brackets t t, which project outward at right angles to the bars. In'this case the shelves are formed with lugs u u, as are also the upright bars or posts, as shown, said lugs having central apertures, and through the apertures of the lugs to a the bracket-arms pass and turn freely therein, so that there is really a pivotal connection between the parts, the said bracket arms or pivots being fixed at their one end inthe apertures of the lugs of the upright bars or posts. This form of shelving is also supported by a cord (shown at t) which passes over a sheave, w.

Although I have illustrated and described my invention as embodied in the form of shelving, it will readily be seen that the construe tion could be employed in the construction of balancing fire escapes and many other devices, such as self-adjustable stairways for ship-landings.

Having thus described my invention,what I claim as new, and desire to secure by Letters Patent, is

1. The combination, with upright bars or posts pivoted at the base, of shelves, said up right bars or posts and shelves having correspondingly-placed lugs thereon connected togethcr by pivots through the lugs, the several points 01' connection of a shelf with the posts or upright bars being the same distance from the lower ends of the upright bars or posts, substantially as and for the purpose set forth.

2. The combination, with a frame-work consisting of four posts pivotally connected with a bed or base plate, of shelves pivotally eonnected with the posts, substantially as de scribed.

The combination, with four posts, as a, I), c, and 11, formed with corrcspontlingly-placcd lugs 0 c and pivotally connected with brackets ff, of shelves at m, formed with lugs 0 o, and thereby pivotally connected with the lugs 0 0 of the posts named, substantially as described.

4. The combination, with four posts, a, b, c, and (7, formed with correspondingly-placed lugs e c and pivotally connected with brackets ff, of shelves formed with lugs 0 0 and pivotally connected with the posts named by bolts which pass through lugs c and 0, and a cord, q, which passes over a sheave, 0', carried by a block, 1-, that is seen red above the shelves, substantially as described.
